[0002] Plant extracts are products made from plants as raw materials. According to the needs of the final product, they are extracted through a physical and chemical extraction and separation process to obtain and concentrate one or more active ingredients in the plant without changing the structure of the active ingredients.

[0003] In order to obtain relatively pure plant extracts, it is often necessary to remove impurities during the extraction process. Currently, there are many ways to remove impurities, including alcohol precipitation, adsorption, membrane filtration, etc. In addition, according to the property that the solubility of the extract increases with increasing temperature, ethanol dissolution and hot filtration can also be used to remove impurities. For example, the patent with application number CN201110192518.6 discloses a method for preparing high-purity betulin, in which the crude product is dissolved in an ethanol aqueous solution, heated and stirred to dissolve, and then filtered while hot to remove insoluble impurities.

[0004] This type of impurity removal method often requires the use of two sets of devices, a dissolving device and a filtering device, and the material in the dissolving device needs to be transferred to the filtering device.

DETAILED DESCRIPTION

[0022] Below in conjunction with the attached Figures 1 to 3 , the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.

[0023] Example 1

[0024] A plant extract impurity removal device, such as Figure 1 As shown, it includes a tank body 100, a filter screen 110 arranged in the tank body 100, a first discharge pipe 120 with a cover or a valve arranged on the top of the tank body 100, a backwashing device for washing the filter screen 110, and a flipping mechanism for driving the tank body 100 to flip. Furthermore, a feed pipe with a cover (not shown in the figure) is provided on the side wall of the tank body 100 and below the filter screen 110 to facilitate the introduction of dissolving reagents such as ethanol; a filter assembly is provided inside the tank body 100 and below the filter screen 110, and the filter assembly includes a central axis 210 arranged inside the tank body 100, a plurality of stirring rods arranged on the central axis 210, a first bevel gear sleeved outside the central axis 210 and located above the stirring rod, a second bevel gear meshed with the first bevel gear, a fixing rod connected to the second bevel gear, and a motor arranged outside the tank body 100 and fixedly connected to the fixing rod; in addition, in order to limit the central axis 210, a limiting sleeve 220 is also sleeved on the outside of the central axis 210, and the limiting sleeve 220 is rotatably connected to the central axis 210, and the limiting sleeve 220 is fixedly connected to the inner wall of the tank body 100 through a limiting rod 230. Furthermore, in order to heat the tank body 100, the side wall of the tank body 100 is also provided with an interlayer, and a heating device, such as a heating pipe, is provided in the interlayer. This is a prior art and is not shown in the figure. Furthermore, a second discharge pipe 200 with a cover or a valve is provided at the lower part of the side wall of the tank body 100. Furthermore, as Figure 1 and Figure 3 As shown, the flip mechanism includes support columns 130 disposed on both sides of the tank body 100; the tank body 100 is rotatably mounted between the two support columns 130 via a rotating shaft 140. Further, the outer wall of the tank body 100 is provided with a flip handle (not shown in the figure), generally, at least three are provided, which are respectively provided on the front and rear sides and the top of the tank body 100.

[0025] Working principle: the crude product and the ethanol solution are added into the tank body 100 through the feed pipe; the tank body 100 is then heated by the heating pipe, and the motor is turned on. Under the action of the motor, the central axis 210 and the stirring rod rotate synchronously, thereby accelerating the dissolution speed of the crude product in the ethanol solution. After the crude product is fully dissolved, the worker stands at the rear side of the tank body 100, first holds the flip handle at the rear side of the tank body 100, and then applies force downward to flip the tank body 100 to the rear side. During the flipping process, the handles are gradually replaced to enable the worker to operate the most Convenient; during the flipping process, the material in the tank body 100 is gradually filtered through the filter screen 110. After the filtering is completed, the cover or valve of the first discharge pipe 120 is opened to release the liquid for the next process; thereafter, the tank body 100 is flipped to the initial upright state, and then, the backwashing device is opened, so that the flushing end is facing the top surface of the filter screen 110, so that the filter screen 110 is backwashed. After flushing, the insoluble impurities adhering to the filter screen 110 fall to the bottom of the tank body 100 with the flushing liquid, and are finally discharged through the second discharge pipe 200.

[0026] Through the synergistic effect of the above-mentioned devices, the dissolution operation and the filtration operation can be integrated into one set of devices, reducing the number of devices and saving costs; at the same time, the transfer time between the two sets of devices is reduced, thereby improving the impurity removal efficiency.

[0027] Further, such as Figure 1 and Figure 3 As shown, the top of the rotating shaft 140 is provided with a first small hole, the top of the supporting column 130 is provided with a second small hole connected to the first small hole, and a limiting column 160 (interference fit) is vertically inserted between the first small hole and the second small hole. When dissolving, in order to improve the stability of the tank body 100, the limiting column 160 is inserted into the first small hole and the second small hole. When filtering, the limiting column 160 can be removed, and the operation is extremely simple.

[0028] Further, such as Figure 1-3As shown, the tank body 100 includes an upper tank 101 and a lower tank 102, the inner cavity of the upper tank 101 is hexahedral; the inner cavity of the upper tank 101 is connected to the inner cavity of the lower tank 102; the vertical projection of the inner cavity of the lower tank 102 is located in the inner cavity of the upper tank 101; a second discharge pipe 200 is provided at the lower part of the side wall of the lower tank 102; the backwashing device includes a hydraulic rod 170 arranged on the inner wall of the upper tank 101, a nozzle 180 arranged at the telescopic end of the hydraulic rod 170, a telescopic pipe 190 connected to the nozzle 180, and a water tank connected to the water inlet end of the telescopic pipe 190; a plurality of spray holes are provided at the bottom end of the nozzle 180; further, a water pump (not shown in the figure) is provided between the telescopic pipe 190 and the water tank. In specific implementation, when backwashing is required, turn on the water pump. Under the action of the water pump, the water in the water tank enters the nozzle 180 along the telescopic tube 190, and then sprays out along the multiple spray holes at the bottom of the nozzle 180. During the spraying process, start the hydraulic rod 170 (the number of hydraulic rods 170 is at least one, and if there are multiple hydraulic rods, it is necessary to ensure that multiple hydraulic rods work synchronously), so that the nozzle 180 moves backward and forward repeatedly in the upper tank 101, and then the insoluble impurities adhering to the filter screen 110 are washed down in all directions. After the flushing is completed, turn off the water pump. In addition, in actual implementation, the direction in which the tank body 100 is flipped is different from the setting direction of the backwashing component. For example, in the utility model, the backwashing component is set on the front side of the upper tank 101, so it flips toward the rear side when flipping. In this way, it can avoid the material from entering the backwashing component during filtration, resulting in material loss.

[0029] Further, such as Figure 1 As shown, the first discharge pipe 120 is arranged at the top of the upper tank 101, and the top wall of the upper tank 101 is arranged to be inclined downward along the direction of the first discharge pipe 120. In this solution, the smoothness of liquid discharge from the first discharge pipe 120 can be improved, and liquid residue can be reduced.

[0030] Further, such as Figure 3 As shown, both ends of the nozzle 180 are slidably connected to the inner wall of the upper tank 101 , so that the nozzle 180 can be limited and supported, thereby reducing the supporting force of the hydraulic rod 170 and improving the movement stability of the nozzle 180 .

[0031] Furthermore, during backwashing, a large amount of flushing liquid will remain on the bottom wall of the upper tank 101, making it difficult to quickly discharge it to the filter screen 110. Based on this, Figure 1 As shown, the bottom wall of the upper tank 101 is tilted inwardly and downwardly. By tilting the bottom wall of the upper tank 101, the cleaning liquid remaining on the bottom wall of the upper tank 101 can fall quickly along the tilted surface into the filter 110, reducing the residual cleaning liquid.

[0032] In the description of this patent, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and the like indicate the position or location relationship based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent.
